针对永磁同步电机常规直接转矩控制系统涉及到的问题,例如磁链的准确观测、定子电阻的变化、电压矢量开关表的改进以及滞环控制器的改进等等,本文都作了详细的分析,并提出了改进方案。为了提高系统的性能,本文将空间矢量调制的方法引入了常规直接转矩控制中,并在此基础上,对永磁同步电机无速度传感器问题作了详细的分析,总结了国内外的研究热点,提出了采用转子磁链矢量为基础的永磁同步电机直接转矩控制速度估计方法。仿真结果表明,该方案具有很好的动、静态特性。(Firstly, the paper analyzes the principle of direct torque control of permanent magnet synchronous motor and elaborates the impact of space voltage vector of the stator flux and the electromagnetic torque.Secondly, the paper introduces direct torque control of permanent magnet synchronous motor SVPWM technology.Under the same hardware conditions,the system can obtain More continuous voltage space vector by taking advantage of SVPWM.The simulation results show the program not only keeps the direct torque control fast dynamic response, but also reduce the motor torque ripple.)

时频分析工具箱
法国中央科学研究院和美国RICE大学共同开发了时频分析工具箱(matlab emd)
是一款非常好用的时频分析计算工具,它是分析时变非平稳信号的有力工具,matlab 时频分析工具箱提供了时间域与频率域的联合分布信息,清楚地描述了信号频率随时间变化的关系。
其中主要含有四种函数:
信号产生函数,可以产生不停类型的信号,如Chirp信号,bpsk信号等。
时频分析函数,可以计算线性、Cohen类、仿射类非线性分析值函数,例如短时傅里叶变换(STFT),Gabor变换,谱图,Wigner-Ville(WVD)等。
分析处理函数
图形显示函数,如等高线、三维图等。(Time-frequency analysis toolbox)

Blind-Channel-Estimation
就通信系统而言,涉及到有线信道及非卫星无线信道的问题时,信道不再可以看成为恒参信道,信号往往是通过未知信道传播,通常把这样的信道称为盲信道。 本源代码对盲信道的参数进行估计,利用matlab仿真,对做盲信道的工程人员有一定的借鉴价值。(On communications systems, related to non-cable channels and the issue of satellite radio channel, channel no longer can be seen as a channel Constant reference signal is often spread through unknown channels, usually channel such as the blind channel. Source code for the blind channel estimation of the parameters, the use of matlab simulation, on the blind channel to do the engineering staff from a certain value.)
